Final Drilling Results from the Cinovec Lithium & Tin
Deposit
Rare Earth Mineral Plc (AIM/ISDX: REM; OTC: REMMY) is pleased to
report the analytical results for the final three drillholes from
the recently completed drilling programme at the Cinovec Main
sector of the deposit.
A revision of the resource model is now underway and will form
the basis of the soon to be completed Preliminary Feasibility
Study. It is anticipated this resource model will be finalised and
announced in February 2017.
REM holds a 20.76% economic interest in Cinovec, via its
interest in European Metals Holdings Limited ("EMH"). Cinovec
contains the largest lithium resource in Europe and one of the
largest undeveloped tin resources in the world.
The full EMH release is available at:
http://europeanmet.com/assets/20170210_-_EMH_Final_Drilling_Results_(Final_Draft).pdf
Highlights from the EMH release:
-- Analytical results for further three drillholes at Cinovec
Main confirmed or exceeded the expected lithium content and
mineralisation widths.
-- The drillholes CIW-25, CIW-27 and CIW-06, are located in a
central part of the deposit, filling a gap between the western edge
of the Cinovec deposit and the historic vein deposit
Cinovec-Central.
-- Hole CIW-25 contains the Company's longest Li intercept to
date of 361.5m averaging 0.43% Li(2) O, incl. a high-grade Li
interval of 14.7m averaging 0.93% Li(2) O. Moreover, significant
intervals of Sn and W are included: 2m @ 1.67%Sn and 0.216% W and
2m @ 0.76%Sn and 0.319% W.
-- Hole CIW-27 retuned a Li intercept of 235m averaging 0.49%
Li(2) O, incl. high grade zones of 14m @ 0.97% Li(2) O and 2m @
1.79%Li(2) O.
-- Hole CIW-06 intercepted a Li interval of 258.5m averaging
0.44% Li(2) O, containing high-grade intercepts of 3m@1.11%Li(2) O,
2.75m@0.91%Li(2) O and 2m@1.03%Li(2) O.
-- The updated drill database and geologic model for Cinovec
have been completed and provided to Widenbar and Associates. The
block model will be updated within the next fortnight, as all the
analyses of the core from the drilling program have been received.
The block model and resource calculation will form the basis of the
Preliminary Feasibility Study.
Drill Programme
The drill holes CIW-25, CIW-27 and CIW-06 were collared in the
central part of Cinovec main, filling a gap between the historic
Cinovec-Central mine and the western edge of the Cinovec deposit
(see Figure 1).
The current drill programme at Cinovec Main has been planned to
confirm and delineate near surface lithium and tin mineralisation
that would provide initial feed to the mill. Other goals are the
conversion of resources from the Inferred to Indicated category,
and delivery of material for metallurgical testing. A total of 17
diamond core holes have been completed. Visual inspection and
logging indicates that the geology in these holes is as expected.
Drill details are listed in Table 1 below.
After geological logging, drill core is cut in half with a
diamond saw. Quarter core samples are selected (honouring
geological boundaries) and dispatched to ALS (Romania) for
preparation and assay; the 3/4 of the core is returned to the core
box and stored securely on site. Samples are being prepared and
analysed by ALS using ICP and XRF techniques following standard
industry practice for lithium and tin deposits. Strict QAQC
protocols are observed, including the insertion of a Li standard in
random fashion for every 10 core samples, as well as the insertion
of blank and duplicate samples.

Mineralised Intercepts and Lithology
The drillholes CIW-25 and CIW-06 were located on the NW edge of
the Cinovec-main deposit, both were collared in the lithium bearing
granite, and are about 60 meters apart in N-S direction at surface,
increasing with depth as their core angles are discordant.
The upper part of the drill hole CIW-25 is formed by albite
granite with several quartz veins and thin near-vein greisen
bodies. The initial interval of massive greisen starts at depth of
104.25m and hosts a high grade intercept of 14.7m averaging 0.93%
Li(2) O and high Sn and W intercepts (incl. 2m@1.67% Sn). The
interval of intensive gresenization is terminated by an albite (+/-
sericite) granite (173.5-204.6m). Below this zone, a long interval
of greisenized granite and greisen was intersected. The base of the
lithium mineralisation, the so called is low-mica granite, is at a
depth of 373m. Apparent core angles of narrow greisen contact were
measured at 55-70 degrees. The drillhole was angled 70 degree West
and the core was not oriented; therefore, the mineralised
intercepts may not represent true widths.
The hole CIW-06 is angled 80 degrees to the North. It starts in
albite granite and is intersected by several quartz veins with high
Sn and W grades. Greisen and greisenized granite zones are more
frequent with depth. This upper sequence of the core is interpreted
as a continuation of the vein domain from the historic Cinovec-Main
deposit (4 historic stopes were intercepted in the hole). Interval
of massive greisenization starts in depth 127.5m. The base of the
Li mineralisation is presented by low-mica granite at a depth of
270m. As the angle of the hole is perpendicular to quartz veins and
greisen bodies, the mineralised intercepts in the hole CIW-06 can
be considered of true, or near true, widths.
Drill hole CIW-27, located some 160m W of CIW-06, is collared in
the barren porphyry. The contact with the lithium bearing granite
is at 102.8m. Immediately below the contact a massive greisen with
quartz veins was intersected. The main mineralised interval is
formed by greisenized granite and greisen, locally with quartz
veins and zones of albite (+/- sericite, hematite) granite. The
base of the main mineralised interval occurs at 339m where the
low-mica granite is intersected. Measured core angles in the
drillhole CIW-27 are subhorizontal, the hole is vertical, therefore
the mineralised intercepts can be considered of true, or near true,
widths.
The Tables below list the mineralised intercepts for the three
drillholes.

"Inferred Mineral Codes, is that part of a Mineral
Resource" Resource for which the tonnage
and grade and mineral content can
be estimated with a low level of
confidence. It is inferred from
the geological evidence and has
assumed but not verified geological

based on information gathered through
the appropriate techniques from
locations such as outcrops, trenches,
pits, working and drill holes which
may be limited or of uncertain

other sampling procedures at locations
too widely spaced to ensure continuity
but close enough to give a reasonable
indication of continuity and where

About Rare Earth Minerals
Rare Earth Minerals invests across the globe, principally in
lithium mining projects. Its primary strategy is taking significant
economic stakes in upstream exploration and development assets
within strategic metals. We identify assets that have strategic
cost advantages that are not replicable, with the aim of achieving
lower quartile production costs. The combination of this approach
and seeking value opportunities allows us to identify projects
capable of achieving high rates of return.
The Rare Earth Minerals board has a blend of mining, commodity
investing, fund management and deal structuring knowledge and
experience, that is supported by access to key marketing, political
and industry contacts. These resources are leveraged not only in
our investment decisions but also in continuing support of our
investments, whether it be increasing market awareness of an asset,
or advising on product mix or path to production. REM's goal is to
assist management to rapidly develop the project up the value curve
and deliver excellent returns on its investments.
Rare Earth Minerals are major shareholders of the Sonora Lithium
Project in northern Mexico and the Cinovec Lithium and Tin Project
in the Czech Republic. Rare Earth Minerals portfolio also includes
significant lithium-based investments the USA, Australia and
Namibia. The Mexican and Czech deposits have published Indicated
and Inferred Mineral Resources of 11.3 million tonnes of Lithium
Carbonate Equivalent.
